This powerpoint presentation begins by providing history and background information of four water utilities in the Michigan towns of
Chelsea,
Davison,
Grand Blanc, and
Saline. The drivers for membrane
technology for softening included:
application of new state-of-the-art
technology for multi-contaminant
removal;
small, modular footprint would save
on building costs;
full automation allowed reduced
staffing requirements; and,
no lime sludge from conventional
lime softening process. Project driving forces included:
regulatory requirements achievable
via membrane separation technology;
capital costs were essential for
project feasibility for smaller
municipal utilities; and,
"Turnkey Solution" was selected to
meet initial budget and schedule
needs in lieu of traditional
"Engineered Solution" approach. Separate costs for membrane softening and the operation and maintenance of membrane softening are given, along with design criteria, membrane treatment system schematic, raw water supply, chemical pretreatment, physical pretreatment, membrane feed pumps, membrane treatment, post-treatment, concentrate disposal methods, construction, start-up and testing, operation and maintenance, and recommended improvements. Includes figures.
